You can add an individual record from any search or browse results to the basket simply by clicking on the record title (assuming that the icon to the left indicates that it is available).
In the results view, you can see whether a record is in your basket already 
, or whether it is available to be added to your basket 
.
Alternatively, you can checkmark the box(es) or select the line(s) by clicking the title line, and click Send # to Basket. To select multiple lines, you can select lines either by dragging the mouse or clicking the lines while pressing the SHIFT key. Currently there is a limit of sending no more than 100 records to the basket. You can also use the "Select All (Max 100)" and "Select None" links to select all or no records with one click.
You can remove records individually from your basket by clicking the 
icon in the upper right corner or by clear your basket (remove all records in it) by clicking on the scissors 
icon.
Additionally, you can remove a record from your basket when you close it after making edits by selecting the "Save and Remove from basket" option in the pop-up.
