Call Number browse - Back-end

Current situation or problem:
Users are able to search the inventory by call number (eye readable and normalized) but the results list contain only records with matching call numbers and do not provide information on which call number comes before or after .

In scope

• Browse by call number
• Browse all cataloged material that have been assigned a call number
• The browse list should display preceding, matching and succeeding call numbers
• Call numbers should be sorted by shelving order but call number should be a base for search/browse
• The user should be able to navigate forward and backward

Out of scope

• Browse by other elements
• Navigating from the detail screen

Here are some examples of the Call Number Browse:

• Michigan State University: https://magic.msu.edu/search/c?SEARCH=pr&sortdropdown=-&searchscope=39
• Center for Research Libraries : http://catalog.crl.edu/search/e?SEARCH=L&searchscope=2&x=0&y=0
• Cornell University: https://newcatalog.library.cornell.edu/browse?authq=a&start=0&browse_type=Call-Number

Questions

• How many preceding and following call numbers should be displayed - it will be made configurable through the properties for the request
• Should the browse list display records that match each call number - this will be implemented
• Should there be a count of items for each call number as in the Michigan State and University of Chicago examples - the count of instances matching searched call number
• Should the results be sortable by other properties than call number - not in scope for Lotus
