Our church has released a new set of liturgical resources, providing collects, sentences and readings which line up with the three year RCL cycle.
Allegedly they "replace" certain pages in our Prayer Book, but I don't know about that as these pages have not been formally approved by General Synod and diocesan synods. (The argument that they simply reorganize resources already approved does not wash with me. Liturgical formularies are about the rubrics, the options (and, in this case of providing just one collect per Sunday, the non-options), as much as about the content of prayers).
Anyway, as a free offering to the life of our church, these resources which have been circulated by dioceses (some or all? not sure) are available online:
For Feast Days
For good collects for each Sunday of the year (as well as for feast days), I encourage you to visit Liturgy weekly.
If you have any comments to make by way of evaluation of the collects in the material I have posted to the above links, please let me know.
