The first XXL data release (hereafter DR1), which is associated with the first series of papers, included the catalogue of the 100 brightest galaxy clusters, published in , and the catalogue of the 1000 brightest point-like sources, published in . A second release (DR2) will occur jointly with the publication of the present paper. A list of the contents of DR1 and DR2 (inclusive of references) is tabulated in section \[SecDB\].

We present here the catalogue of all the sources used for DR1 and DR2, from which the above DR1 catalogues were drawn (as well as a recent study on the environment and clustering of AGN, , also known as ). After DR2, the XXL collaboration plans to reprocess the data with an improved pipeline, described in .

The plan of the paper is as follows. Section \[SecXray\] presents the X-ray data, the X-ray processing pipeline (\[SecPipe\]), and basic properties such as sky coverage, $log N-log S$, and flux distribution (\[SecInfo\]). Section \[SecMW\] presents the multiwavelength data, describes the counterpart association (\[SecIdent\]), provides some statistics (\[SecMWStat\]), presents the spectroscopic redshifts (\[SecOurSpe\]), and describes the additional spectra obtained with the AAOmega spectrograph in 2016 (\[SecLidman\]), supplementing
