There is an indication that many authors use journals in libraries as sources for citation articles either by reading or photocopying rather than request...

In the UK pond numbers declined from approximately 800,000 in the nineteenth century to 200,000 by the 1980s. Since then pond numbers have started to increase.

This oration, and the record of it for publication, mainly focuses on the new Royal Victoria Hospital building opened officially on 2 September 2003, but it is interesting to compare and contrast the needs of the Royal Victoria Hospital at the ends of the 19th and 20th centuries. At both times there was increasing dissatisfaction with the hospital's accommodation while the demands on the hospit...

Although the use of committal has been seen by clinicians as an impediment to care [2] and clinicians continue to have concerns about the timing of discharge from the act [3], many people with serious mental illness have...
