Without exception, all services (the "Offices") in the Early Church were sung or chanted, as this enabled people to focus on the meaning of the words, and for them to be seen as prayer.
With Chanting, in particular, it is the words which are important, with music acting to support the words, rather than singing in which music is the focus, with words as an adjuct.
This page focuses on books which are available and in print (as at the time of writing), and can be obtained usually from online retailers or other sources.
Traditionally, chanting was done in the local language, and the chant reflected the host language. In Western Christianity, which had its main period of evolution in the first millennium, this tended to mean Latin, which after the first century was standard. Traditionally it is referred to as "Gregorian Chant" in honour of Pope Gregory 590-604, who did much to popularise it, although actually it was in use before then.
Initially chant was not written, but transmitted aurally (in some churches - such as the Coptic Church this was still so), and was not written down, as one learned by listening, and in any event was not uniform. All cantors though did not have equal skill, and around 800-900 AD, chant music started being indicated by "neumes" (squiggles over the words to indicate whether the pitch went up or down, but initially no absolute level of pitch). about 1000 AD and later, the earliest manuscripts started appearing using a 4-line stave, and this is still in standard use for Gregorian Chant.
The Rule of Benedict, developed as a framework by St Benedict (who lived 480-547), recommended that Christian Communities chant all 150 psalms every week, and that they be divided between 7 services every day - the main services being Lauds (also known as Morning Prayer or Matins) and Vespers (also known as Evening Prayer or Evensong), a long Night Office of psalms and readings before dawn, and shorter services to be chanted from memory in the workplace or in bed at night.
At the time of the Reformation, Chant in English appeared, the feature of Anglican Chant was that it was polyphonic - typically with 4 voices in harmony, and the division of Psalm verses into two parts, with a framework of 4 chords in the first part of the verse, and 6 chords in the second. The Reformed Church split the psalter chanting over 2 daily services only (Morning Prayer and Evening Prayer), with the psalter being chanted over 30 days, rather than every week. This revised arrangement was also advocated for parishes and families, rather than being the aim of religious communities.
The use of the old Gregorian Chants from early days was revised in the 19th century, and these books are still in print, based on the Book of Common Prayer as revised in 1662.
At Vatican 2, the Roman Catholic Church, while retaining weekly psalter coverage ("Monastic"), also introduced splitting the psalter over 4 weeks ("Roman" Use). Both these variants are in print (mainly in Latin, but also in German. English versions are rare, usually very simplified). "Pointing" in many psalters was also introduced (following Anglican experience) showing where repeating notes changed. This makes it easier for people who are not chanting the psalter frequently to sing together, but Gregorian Chant pointing is more complex than Anglican with different syllable allocations for different musical tones.
The Lutheran Church has issued various chant books in German and English, on various bases.
Books (weekly psalter) aimed at a monastic audience, tend to be more complex with different variations, 4-weekly psalter more bulky as there are 4 weeks to be covered, but easier to follow.

6. Anglican Use
6a. St. Stephen's House, Oxford - Office Book. Contains Morning and Evening Prayer in Common Worship format, but traditional language, and Gregorian Chant - all in English. Much page flipping. Full pointed psalter and a good selection of hymns in Gregorian Chant. Sanctorale and Temporale. Requires a Bible for the Bible readings. Contact officebook@ssho.ox.ac.uk Pricing at the last count was strange: £25 for the first copy, and £12 for subsequent copies.
6b. Anglican Chant. Many books. Often Chant books are sold separately from the psalter, as any chant tune will fit any psalm. Check if buying a psalter that it is pointed. It is very hard to sing reliably from unpointed text. Most books based on Book of Common Prayer 1662, but recent ones from Common Worship also pointed.
6c. Anglican Use - Gregorian Chant. Main book is Manual of Plainsong by Briggs and Frere which provides Chant to Book of Common Prayer 1662 (Coverdale psalms). Pointed. The 2000 edition in print is paperback, and glue bound, so pages tend to fall our. The 1902 edition is widespread in second hand shops and easier for a beginner to sing from, although it looks old fashioned. Each psalm is allocated a single chant tune, which irritates purists.
7. Orthodox Church - Western Rite. The Antiochian Orthodox Church and other Western Rite Orthodox churches in the USA are bring back into print various of the Anglican Chant books.
7a. St Dunstan's Plainsong Psalter. Based on Briggs and Frere, but converted to the Anglican 1928 Book of Common Prayer. Available from the Launcelot Andrewes Press in the USA and other sources. A well made hardbacked book.
7b. Monastic Diurnal and Monastic Diurnal Noted. Two very different books: The Monastic Diurnal (note: OUP nor Farnborough edition) is a reprint of the 19th century Anglican Monastic Diurnal, a very compact book based on 19th century Monastic Breviary, using Coverdale (BCP psalms and canticles). Unpointed. The Monastic Diurnal Noted is a large book with music handwritten, intended to be used with the Monastic Diurnal, but tying the two in together is not easy. Both available from the Launcelot Andrewes press.

8a. Lutheran Liturgical Prayer Brotherhood (USA - Missouri Synod) see http://www.llpb.us English. Psalms on weekly, 4 weekly or 30 day cycles. Pointed. Lutheran Chant is slightly different from Gregorian Chant.
