Cataloguing Matters: being part of the information landscape

/ Jane Stevenson

Consider the following questions, which use the topic of design history, but could be for any topic area:

Where did this person work?
Who did they know? 
What can I find out about furniture design in London in the early 20th century?
Who designed this early 20th century chair? 
Did the designer feature in this exhibition? 
Can I find photographs of this section of the exhibition?
Did these designers both feature in this design exhibition?
Who influenced this designer?

These are surely typical questions for researchers.  They are the sort of questions we thought about when we were working on Exploring British Design. But these questions do not start with the archive. An archive collection may well hold many answers for  these questions, but there remains the problem of connecting these questions to the archive: ‘I’m interested in this designer/in this chair that they designed/in this exhibition they designed for’. We need these questions to lead to archival sources when appropriate.

Which comes first, the research question or the archive? We tend to assume the archive, but for many researchers the question comes first and the archive is, at that point, not known to them. We become a little fish in a very big pond when we enter the Web, and so we need to find ways for researchers who may not be aware of us to hook our collections.

But how do we achieve this? We often have to work within considerable constraints and we cannot simply transform our cataloguing practices.  There are many technical solutions that we can potentially make use of, but I think the first challenge lies with the data itself.

Individual archive repositories may think that there is no way they can move into a Linked Data world of RDF and triples and persistent URIs. But I think there are steps that we could take to help our descriptive data better fit this kind of landscape and have the potential to be more ‘linked in’ to other sources and to researchers’ paths of discovery.

Our descriptive practices tend to treat collections as stand-alone entities, rather than integrated parts of a whole information landscape. We do not think enough about cataloguing in a way that facilitates an integrated approach where we can connect to other information resource and allow researchers to come to archives through searching for people, organisations, subjects, events and places, and to come to them as part of a whole network of resources.  I think we need to try to think about providing potential ‘connectors’ within our descriptions that will allow them to be hooked into the landscape more effectively.

Here are some thoughts about how we can help to achieve this:

Be consistent when cataloguing

This may sound straightforward, but having looked at thousands of descriptions from well over two hundred archive repositories, I can announce that it doesn’t always happen. For instance, simply entering the name of the repository in the same way for every catalogue entry, and not adding the repository code as part of the repository name, for example, ensures that the repository is always correctly identified. This means that all of the collection descriptions can be clearly identified as being from the same institution.

When entering names, think about how you structure them. Many archive systems provide a means to store and link to names, and yet it is amazing how often one name varies. If nothing else, think about adding life dates to a name, which helps with unique identification.

Here on the Archives Hub we have to hold our hands up for a potentially unhelpful practice up till now of encouraging the creator name to be entered in one way under ‘name of creator’ and another way as an index term. This reflects a time when we were less focussed on machine processing. Of course, it is much better to enter the name consistently, so that the connection can clearly be made.

Try to use rules and standards

Whilst I have increasingly become somewhat frustrated by our standards, I still think there is a role for standards to encourage consistency, clarify meaning and help draw things together. If you enter subjects using UKAT or LCSH, then try to ensure that all your terms really do come from these thesauri. We get examples where the thesaurus is named, but the subject is not actually from the thesaurus.

When entering things like language codes (ISO standard 639), take a few minutes just to find out about them. They need to be lower case, to be consistent. It’s worth having an understanding of what you are doing and why.

Do the same for dates. Think about what a normalised date is and why it is important. It is really worth having a sense of why these things matter. ISO8601: “The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times”. That sounds perfect for archives, and well worth adopting.

Think about the questions people ask

One of the advantages of indexing is that it gives you a chance to consider the terms you can best use to ‘advertise’ your collection. It is really good to if the scope and content text is clearly reflected in the index terms. If your archive is about a designer and you have described things they have designed, then you might realise that you haven’t used ‘furniture designer’ in your text, but this is a good index term to use.  Or maybe the archive is really useful for those looking at the history of design education, but you haven’t yet actually used the term ‘design education’ in your text. You can add it as an index term.

Try to think beyond the UK

This may again sound obvious, but unfortunately NCA Rules don’t exactly encourage this, even if they don’t prevent it. When indexing by place name, add the county and certainly add the country. Indexing really helps us think about this. Consider a typical biographical history entry:

Charles Edward Sayle was born in Cambridge on 6 December 1864. He entered New College, Oxford, in 1883, and St John’s College, Cambridge, in 1890.

It wouldn’t look quite right putting:

Charles Edward Sayle was born in Cambridge, England, on 6 December 1864. He entered New College, Oxford, England, in 1883, and St John’s College, Cambridge, England, in 1890 [etc]

And whilst it would help with identification, it is still unstructured. Much better to ensure you have:

Place name: Cambridge, England

in your structured index terms. True, there are plenty of ways to mark this up, some better than others, but at least having an index term entered in this way is a great help with uniquely identifying the Cambridge that you mean, as opposed to the one in the US or New Zealand, Australia or Jamaica. It means that a researcher who is researching a topic around ‘Cambridge, England’ is more likely to find your description.

If you put your place names into some kind of specific field, try to avoid something like ‘Cardiff, Merthyr Tydfil, Cambridge’ (an example from the Hub) or ‘Cambridge etc’ (another example). So if your cataloguing software provides  just one box for place, repeat that box for each place, rather than putting a load of them into one entry. If it allows for something like place name and country, use that to your advantage.

Put index terms into the most appropriate categories

On the Hub we’ve had plenty of family names as personal names and personal names as corporate names. But most commonly we get genre as subject. If your archive contains photographs, press cuttings, preliminary sketches or parchment (animal material) and you want to make this known, you need to index by material type, not by subject  ….unless the archive is about photographs or about parchment.

Think Reference!

Your references should give the ability to uniquely identifying every part of a hierarchical archival description. Think carefully about adding them and make sure you have a unique reference at every level of description. Some archival software will automatically generate references, which does help because then they will be consistent and unique. But if you add them manually, it is very easy to make a mistake. On the Hub we found several hundred duplicated ‘unique references’ when we went through a major exercise to clean up references. And I do mean several hundred, not one or two.

Optimise titles for search engines

All of this structured data really needs the boost of descriptions that work well on the Web, simply in terms of being discoverable. SEO, or search engine optimisation, is a big topic, and your system may not allow you to make many changes, but in terms of the actual data, do think about appropriate titles, which are a really good hook. Include the most significant words, make sure that are not too long (so they are easy to scan for a researcher looking through various sources) and make titles at collection level self-explanatory. At lower levels this is not such a problem, as it is possible to append the collection title, to help with interpretation.

Look at how your data exports

This may not be possible or practical for everyone, but if you can do it I think it is a really good indicator of how interoperable your data might be to see how it looks when it is exported, because that is when you are removing it from the comfort of your own familiar system, and potentially unleashing it into the world.

The Event Horizon

I am particularly interested at the moment in events. History is made up of events. Who’d have thought it, when our standards barely mention them!

EAD (Encoded Archival Description), our XML standard for descriptions, doesn’t allow for events to be indexed at all.  CIDOC CRM is “a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation” and it is event-based. It may be a complicated beast, not much used within our domain, and many of you won’t be aware of it, but there is certainly something to be said for putting events at the forefront of how we think.

The new EAC-CPF standard allows for chronologies in the biographical section of the description, but this is more about narrative (a list of events as part of one name authority description).  It is based partly on ISAAR(CPF) which states “Record in narrative form or as a chronology the main life events, activities, achievements and/or roles of the entity being described.”  Narrative form is fine for a researcher who is perusing the description, but structured form that is not necessarily so closely tied to narrative is what is required for more integration of data.

People, organisations, places and subjects are all linked by events – that is where the connections and the stories are. I think it is a major shortcoming of our standards that events are not given more prominence.

I mention this here really just to say that whilst we can improve our descriptions, and think about consistency and indexing, I do think that there are things around cataloguing that may require a more fundamental change.

Research Questions

Coming back to the initial questions I asked. Our cataloguing can help to ensure that archives are networked in to the broader information landscape. This is not about whether the archive can in principle answer these questions. It is about whether a researcher asking these questions (maybe initially through Google, maybe through other generic channels) can discover the archive as one source amongst many:

Where did this person work?
Uniquely identify the place(s).

Who did they know? 
Make sure names are consistent and try to make them unambiguous.

What can I find out about furniture design in London in the early 20th century?
Use appropriate index terms and think about how to add dates consistently.

Who designed this early 20th century chair? 
Adding index terms helps to draw out significant names and concepts

Did the designer feature in this exhibition? 
Entering the exhibition name and designer name as structured data will help.

Can I find photographs of this section of the exhibition?
Make sure you have the exhibition name clearly stated and think about using index terms for formats – these are a great means for researchers to find types of material. But remember, this is ‘photographs’ as a genre or form, not as a subject!

Did these designers both feature in this design exhibition? 
Not so easy, as we don’t index by event type

Who influenced this designer?
Not so easy, as we don’t tend to provide structured relationship information to connect people other than in the broadest possible way (these two people were ‘associated’). But that is another story…

 

To my mind, cataloguing is a skill, and it is really worth thinking about what you are cataloguing and how you catalogue it carefully. It is more important to think about this now than it was 30 years ago, because 30 years ago we were working with with narrative descriptions and index cards. Now we want our data to be interconnected.

 

 

The Quest for Single Search

/ Jane Stevenson

This post is based on a report published by OCLC Research, Single Search: The Quest for the Holy Grail (Leah Prescott and Ricky Erway, 2011).

It is less than ideal when users can benefit from a single search option for  resources across the internet, but within an institution they are presented with a range of search systems for different services and resources. A single search obviously allows researchers to search across the organisation’s resources; it may also give a sense of the rich resources of an organisation and may provide a motivation to build upon them.

The OCLC report is based upon discussions with nine organisations that have implemented single search. There are certainly substantial challenges, not least the resources required and the need for effective collaboration across an institution. But it is clear that single search, if it is provided effectively, will help researchers and will help to harmonize collections management.

image of a mazeSingle search needs to simplify rather than complicate the user experience, and sometimes the challenges this poses are not addressed and a single search ends up being a frustrating or confusing experience. We know that some users find navigating archival hierarchical descriptions confusing; adding library and museum items to this increases the challenge. Different collections may be catalogued very differently and to different levels of granularity, so presenting a coherent list of results is not easy. Added to this, many institutions now have digital collections, but only a part of their resources are digitised and so there is a need to indicate clearly what is digital (what can be accessed digitally) and what requires a visit to the institution.

The OCLC report refers to single search having the ability to ‘fundamentally change how an institution identifies itself’. Maybe if the single search represents a large part of the resources of an institution this is true; it is not likely to be the case in a university, where the collections are only a small part of the university’s business. Single search may enable curators, archivists and librarians themselves to get a more coherent view of the collections. This could be a useful advantage, as we know that often curators in charge of one collection or subject area do not necessarily have a good understanding of the whole. It may encourage a more efficient and streamlined approach to collections management.

Amongst the nine institutions that formed part of the OCLC discussions, some did have a mandate to create single search, but even with this kind of directive, there is a need for senior managers to provide the resources required and ensure that it is made a priority. In addition, the isssue of individual motivation is significant. I think this is a fascinating area that is sometimes overlooked: The extent to which the staff involved are motivated to work together and to achieve a vision must have a substantial impact on the outcome. What sort of role to ‘champions’ play? How important are they? Does it come down to individuals with intellectual curiosity and the willingness to learning new skills and change working habits? Is it important for the institution to foster this kind of attitude in order to ensure that innovations like single search are likely to work? One of the institutions in the OCLC report referred to the staff that had been selected to work on a single search as being selected for their ‘interest, skills and capacity to work on the program’. I have certainly come across colleagues who are frustrated by a lack of co-operation from other staff, which can significantly hamper any kind of innovative changes to metadata creation and cross-searching.

I think that attitudes are key to success in a project like this, where working practices may have to change and habits may need to be broken. It reminds me of that great YouTube video of the lone dancer who is joined by just one person – one is a crazy lone dancer, and others tend to try to ignore him/her; but once just one person joins in you have a group, and once you have two, then you’re more likely to get three, then four, and then the group builds up to the extent where those who are reluctant to join in anything a bit new or different, where they might embarrass themselves, end up joining in because not joining in becomes the exception rather than the rule. It’s a slightly different scenario but the point is similar.

The size of the institution is likely to have an impact. A small institution is often more agile, and getting buy-in may be easier, although there may be less resource to draw on. Maybe for a large organisation, trying to implement something that cuts through the departments and teams in a very horizontal way, like single search, is harder if the organisational structures remain the same. The priorities of the different departments involved may end up pulling against the project. It becomes all the more important to define the goals, get buy-in at the right levels,  have clear and effective communication channels, and also find an effective way to keep the momentum and motivation going.

The OCLC report makes one observation which resonates very much with me: ‘It is important for the success of the project to have representation…from IT units, as weak motivation within the IT area of an organization has the power to paralyze such a project.’ The important thing here seems to be to ensure that the right people are included at the right stages in the project. IT should be brought in right at the outset and a real effort should be made to develop not only a common understanding but also a feeling of good will and strong motivation.

As the OCLC report states: ‘The reality of achieving an integrated access vision could mean overturning years or decades of institutional thinking, which has segmented collections management practice among the three different sectors of LAMs.’  Professionals within libraries, archives and museums have their own perspectives and values, and are often very caught up in their own long-standing practices. There may be good reason for this – often curators and archivists have had to fight over time to ensure their collections are properly looked after and catalogued. But a single search may call for a more compromised approach, and certainly it is likely to call for different thinking and finding new ways to represent the collections.

The ‘Technological Considerations’ section of the report is well worth reading, giving a short summary of some of the options. This is an area where the Archives Hub is very well aware of the pros and cons of different approaches. For an institution wanting to implement single search, there are a number of approaches: systems where you adopt batch export; systems where an API is used to pull the data in dynamically; a single system that replaces all the separate systems or multiple systems harvesting to a central repository; a federated search where each separate system is queried and results are brought back and presented to the user; a central index that is searched rather than the individual systems. All of these have pros and cons around things like flexibility, speed, currency and professional practices.

Of course, a further very important consideration will be digital assets, and the need to take a systematic approach here. Institutions may have Digital Asset Management Systems, but do these operate effectively with other collections sytems? Do digital assets exist in the different collections management systems? Are there shared metadata standards for digital assets?

Metadata Considerations present a whole new raft of challenges. I think that all to often those outside of the domains – maybe the managers who want to see single search and a more integrated approach – do not appreciate the substantial differences in approach between libraries, archives and museums. It is thought that because they all have something to do with that nebulous concept of ‘cultural heritage’ that they should all play together relatively easily. But each domain has built up its own world-view over many decades; the development of standards and best practice involves a great deal of hard work. It could be argued that finding ways to present catalogues or finding aids to users in a way that is as simple and straightforward as possible is not compatible with single search. It may be that single search, while seeking to provide an integrated approach, actually creates a more complex interface as a result of trying to integrate collection-based and hierarchical archival descriptions, item-based museum artifact descriptions and largely open access and usually non-unique library collections.

One of the biggest problems is that metadata is expensive to create. Automated metadata provides one solution but it is a very partial solution, especially for unique archival and musuem collections. Another challenge is that usually metadata has been created over long periods of time using a variety of systems, sometimes migrating from one system to another (often with patchy results). Metadata is messy, and yet standards lie at the heart of effective integration. But even standards are usually at different stages of evolution, and standards adopted by each of the domains do not necessarily harmonise very well.

One of the issues we have noticed on the Hub is the tendency for collections that are catalogued in great detail can overwhelm more summary descriptions. It can give the effect that those catalogued in more detail are more important. If you search on the Archives Hub relatively frequenly, you are likely to come across ‘University of Liverpool Staff Papers’ because they have been very thoroughly catalogued. There may be really good stuff in there, but should this one collection seem to be so much more important than so many others? Yet detailed cataloguing is surely a good thing?

There are also issues around vocabularies, and the tendency to implement multiple vocabularies within the same community. The Hub allows for any recognised vocabulary to be used for index temrsm but that does mean personal names, for example, entered using NCA Rules or AACR. You will inevitably end up with several different entries for the same name. The OCLC report refers to the need to harmonise metadata, trying to standardise terms, but I think that for us the way forward is generally to try to use the ever increasing sophistication of data processing tools to get round this problem, becuase we will never get 200 institutions to put things into the system in exactly the same way. Having said that, we are finding that as most of our contributors use our EAD Editor now, the descriptions are much more consistent and easier to integrate.

The OCLC report ends with some advice on the user interface, and one comment that I wholeheartedly agree with is the advice to hire or consult professional designers if you possibly can. Web presence is so important and Websites are often quite poorly designed. An ideal is to carry out user testing, but having done this ourselves, we know just how much time and effort it can take, and for many archives this is really quite a barrier. Even just testing with a small handful of users is very worthwhile. It’s amazing how much you find you have taken for granted that researchers will question. It’s good to see the importance of rights management emphasised and the need to clearly define access to content. This is becoming increasingly relevant, as data is republished, shared and recombined.

Single search is an important goal, not least because ‘the challenges inherent in this information divide ultimately expect researchers to compartmentalize their interests in a similar manner, rather than encouraging more multi-disciplinary approaches that focus on the research inqury (rather than the nature and custody of the resources).’ Our appoach has tended to suit our own professional outlooks; it should be geared towards what researchers want and need.
