This is the third in a series of blog posts highlighting some of the new or improved features which will be available in the redeveloped SUNCAT. In this post we are going to focus on the latest version of the exact title index.

Basic and advanced search along with browsing will provide users with an exact title index.  The index will be available from a pull down menu on each of the pages.

Searching by Exact Title

We have spent a lot of time and effort to decide exactly how ‘exact’ the index should be. Our first consideration was whether we should actually include a separate index or if the title keywords index would prove sufficient. However, we believe that an exact title search is very useful for “known” item searches, so that when users know precisely which title they are interested in, they can quickly and efficiently focus in on finding where that particular title is held in the UK.

After several false starts, the first of which some of you may have seen when the service was previewed in April/May, we have defined the following rules for the exact title search (for now at least!):

1) It is case insensitive e.g. searches on NEW YORK TIMES, new york times and NeW YoRk TiMeS will all return the same matches.
2) Special characters are ignored, we are currently defining special characters as !”#$%&'()*+,-./:;<=>?@[\]^_`{|}~ after further testing and feedback these may be tweaked.
3) Diacritics are ignored e.g. search terms containing an e will find ê and so on.
4) If a title has a skip in filing defined it matches with and without the skip in filing value e.g. a serial that has a MARC 21 245a tag of

245 04$aThe journal of Hellenic studies /$cthe Society for the Promotion of Hellenic Studies.

will get a match for either The journal of Hellenic studies or journal of Hellenic studies.

5) No partial matching, e.g. a search on New York Times will only match serials titled New York Times not New York Times Supplement.
6) It will only find matches if all the words in a search entry are in the correct order e.g. a search on New York Times will match New York Times but not York New Times.
7) Trailing whitespace at the beginning and end of an index value will be ignored.

The actual MARC 21 tags/subfields we build the exact title index from in the redeveloped SUNCAT are as follows:

1) 245 abnp (Title Statement)
2) 246 abnp (Varying Form of Title)
3) 210 a (Abbreviated Title)
4) 222 a (Key Title)

This is a significant decrease from the number of tags/subfields that the existing SUNCAT service uses for this index so we hope that this should result in directing users quickly and easily to information about specific titles of interest without the distraction of also seeing similar or related titles.

The default title keywords search will remain as a much more inclusive index, enabling users to search across MARC fields concerned with not only the main title entry but also uniform titles, related titles, continuing titles, series titles etc. – in total indexing around 30 MARC tags. As the default search this will continue to allow users to find information when they are less sure of or less specific about the titles they want to retrieve.
