The facet I started with to get my first source was "funds allocation." I used the thesaurus to locate subject words used in the controlled vocabulary. The thesaurus search retrieved the following subjects: Finance, Libraries/Finance - which had Budgets with 589 records. It said it was used for "allocation of funds" and "library budgets."
I used the 589 records hyperlink to see what records were there. I then narrowed that down by the "New Search by Subject" option. I chose "school libraries/finance," which had 232 records.
The source I chose to use as my "known source" to begin my pearl growing was: Farmer, L., et al., (2009 April). "School Library Journal's" spending survey. School Library Journal, 55 (4), 38-44.
The subject terms used from this source were: school libraries/finance, school libraries/statistics, School Library Journal.
SS1: school libraries AND finance AND acquisitions
*Ran as a "subject(s)" search and retrieved 8 records.
*Identified one that sounded promising:
"Schools spend less than ever on books." (December 1995). Library Association Record, 97, 644.
Subjects gleaned from browsing these records: budgets, tax campaigns, school libraries/acquisitions
SS2: school libraries AND budgets AND acquisitions (all used as subjects)
*Records: 1, but it was a great hit for what I was looking for. It was: Reference question. (Fall 2009). The School Librarian's Workshop (30) 2, 15.
Subjects identified with this source: Electronic reference books/ acquisitions; Reference books/acquisitions; School libraries/reference services.
SS3: school libraries AND electronic reference books AND acquisitions (all used as subjects)
*Records: 1 (same as previous search)
Reflection:
I was very satisfied with the pearl growing search method and the results I retrieved on Library Literature.
