The announcement by UCL that all the institution's research is to be freely available is good. Rapture! But I went to the repository at http://eprints.ucl.ac.uk/ and browsed the Greek and Latin area. The very first paper, Robinson, M. (2009) Ardua et Astra: on the calculation of the dates of the rising and setting of stars. Classical Philology, 104 (3), is 'restricted access'. Never mind I thought, it is marked as being in press. I tried another, on the Sappho poem discovered a few years ago:
Rawles, R. (2006) Notes on the interpretation of the 'new sappho'. Rawles, R. (2006) Zeitschrift für Papyrologie und Epigraphik, 157 . pp. 1-7
Again, no copy on the UCL site, only a link to the Zeitschrift für Papyrologie und Epigraphik site, and as far as I can see nothing later than 2004 is available. So, modified rapture.
