Boston Library Consortium
Some of the scholarly books and articles (as well as primary literary texts) that you are seeking may not be available in BC's Libraries. Perhaps you learn from WorldCat that a work for which you are looking is available at BU, or Tufts, or Northeastern or some other local library. Remember: you are eligible to obtain a Boston Library Consortium (BLC) card. The BLC is a cooperative association of nineteen academic and research libraries, many in the greater Boston metropolitan area. A BLC card is used to gain access to, and to borrow from, member libraries of the consortium. To obtain a card contact the reference desk in O'Neill.
If the work you want is not available at BC or at another local library (or if you do not wish to travel to another library), utilize BC's Interlibrary Loan service. One may request the Interlibrary Loan Office (3rd floor O'Neill) to obtain material not possessed by the O'Neill Library. Details of the book, article, etc. may be filled out on an electronic Interlibrary Loan Form accessible on the Interlibrary Loan page. One may also initiate an ILL request from several OCLC First Search databases, WorldCat being perhaps the most prominent.
