[OPEN-ILS-GENERAL] Proposed changes to browse indexes

Hi, Don,

Although this is a separate issue from the current proposed changes, 
it's an interesting question and one I know you have raised before. 
It's a question we've just begun to discuss here, and I feel like we 
need more experience with browse to decide exactly how it should work.

The fact that headings in records work so differently than the headings 
in the browse display is why we chose to use a different separator in 
browse.  We had some trouble when we first moved to Evergreen 
understanding how subject headings in records worked until we changed 
the separator to the greater than sign, which helped people see these as 
breadcrumbs.  The headings in the browse display are treated as one long 
string, and we thought the dash conveyed that better.

When a user is looking at a record like this one:
http://evergreen.noblenet.org/eg/opac/record/1458151?locg=1

They will see some very specific headings like this:
Children > United States > History > 18th century > Activity programs

The user can currently decide to click on only part of the heading to do 
a less specific search -- for example, if they click on "18th century" 
they will find a lot of books on children in that era that aren't 
activity programs, which can be useful.

I can think of a few ways the heading links from records could work:

1.  The same way they do now
2.  Take you to the browse index page in the neighborhood of that 
heading: http://bit.ly/browseoption1
3. Take you to the directly to the records using the heading (the 
equivalent of clicking on the heading in the browse list in #2.)  In 
this case, there is only one record with this heading so you'd be 
jumping back to the record.  Perhaps with this option, the headings in 
the record would need to show the number of records, like the browse 
page does.
4. A hybrid model that lets the user choose just a partial heading (for 
example, Children > United States > History) and it's treated one of the 
options in #3.

We've only had browse up for a couple of weeks and have not really given 
this issue enough thought to know how we'd like the headings in records 
to work, and that may be true of others as well.  But this is definitely 
an issue that I think the community will want to discuss, and to make 
sure that we get as much input as possible from public service librarians.
