Perform some subject searches on the Library of Congress catalogue, by choosing ‘Browse’ and using the ‘SUBJECTS beginning with’ option.  Conduct a search for any term, such as ‘Cats’ or ‘Libraries’.  You will see a list of headings, with the subject terms on the left and the type of subject heading on the right.  Check those to identify which headings are Library of Congress subject headings.

Note how many headings are ‘strings’ of terms.  Can you interpret them correctly?  Click through various headings to the records that include them, and see if the resources are the kind that you were expecting.

Log into SCISData, choose the SCIS Catalogue, then search by ‘Subject’ repeating some of the searches you did in the Library of Congress catalogue.  Again you will be taken to lists of headings.  Those identified as SCIS subject headings are the ones you are looking for.  What similarities and differences to LCSH have you noticed?

I initially did a Library of Congress search for ‘dogs’, and as Lisa said, there were so many results to the point where it was almost overwhelming.

I then did a search for ‘Pompeii’, where I found the subject headings and strings to be more useful and not quite as overwhelming (perhaps because there’s not as many terms/resources?). I could see this being a useful search strategy to narrow down relevant resources:

When I clicked on the subject heading ‘Pompeii (Extinct city)–Civilization, it brought up the 13 resources relevant to this topic. I found it interesting that when I typed the terms ‘Pompeii civilisation’ directly into the search bar it took me straight to one resource rather than bringing up all the resources that were listed under the subject heading, while the search terms ‘Pompeii civilization’ showed 81 search results. Clearly it’s not a perfect system and the differences in language (e.g. US spelling vs. Australian spelling) create issues. However, I still think that it’s a useful tool for when we need to find information on a particular subject.

I clicked on Joanne Berry’s book “The Complete Pompeii” and saw that there were three different LC subjects assigned to it, which would also be useful for someone looking to find other related relevant resources.

When I conducted the same search on SCIS, there were fewer results but they seemed more relevant to a school search:

To further test the functionality of these subject headings, I then tried a search for the books based on the stories created by Critical Role. This created an extra layer of difficulty for the cataloguers, since these comics are a) based on a Dungeons and Dragons Twitch game, so not exactly traditional media; and b) created by a group of actors before being c) adapted into comic book form. When I searched the LC subject heading ‘Dungeons and Dragons (Game)–Fiction’ a number of titles came up, including one title relating to the Critical Role universe: ‘Kith and Kin’. However, none of the actors in the original Twitch game are listed as authors; considering most fans of this show would search for resources using the names of the original actors/creators, this might make it difficult for users to find this resource. In SCIS the same author issues arose; for one resource the actor who created the world and ran the original game the stories are based on (Matthew Mercer) is listed as a contributor, while for another he’s not listed at all, despite being the first name on the cover:

Plus, neither Dungeons and Dragons nor Critical Role are listed as subject headings!

I guess it just goes to show how complicated cataloguing is, and despite the best intentions of the people designing these systems, sometimes (perhaps due to lack of familiarity or new forms which defy traditional standards) they’ll create a catalogue record which is unlikely to be easily found by users who aren’t familiar with cataloguing standards. It’s another reason why it’s so important to have trained teacher librarians recognised as information specialists in schools!
