Brief details are given of how to install and use the library together with the PDF sets available. We also describe LHAGLUE, an add-on PDFLIB look-a-like interface to LHAPDF, which facilitates using LHAPDF with existing Monte Carlo generators such as PYTHIA and HERWIG.8 pages, 5 tables; Contribution to the HERALHC workshopHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
