This is a relatively new journal (2006 is vol. 3) and is available online to University members (on campus only, I think) via http://pats.atsjournals.org/.
Vol. 3 no. 3, for May 2006, includes material from an NHLBI / Cystic Fibrosis Foundation Workshop and presentations from a symposium entitled Linking outcome and pathology in chronic obstructive pulmonary disease.
Clinical Sciences Library is also receiving this journal in print.
